Html To PDF in CakePhp Using html2pdf Hangs

I use html2pdf, which is based on TCPDF, in CakePhp to render Views in PDF. However, sometimes the generation hangs, I mean the browser freezes and never receives data.

There is a way to debug such a behavior? In apache logs I do not see any kind of error...

$this->set(compact('quotation','company','user'));
$view = new View(null, false);
$view->set(compact('quotation','company','user'));
$view->viewPath = 'Quotations';
$view->layout   = 'preventivo';
if ($quotation['Quotation']['quotation_type'] == SERVICE)
{
  $content = $view->render('print_s_template');
  $this->set(compact('content'));
  $this->response->type('pdf');
  $this->render('print');

the print.ctp has 

App::import('Vendor', 'HTML2PDF', array('file' => 'html2pdf'.DS.'html2pdf.class.php'));

$html2pdf = new HTML2PDF('P','A4','it');
$html2pdf->WriteHTML($content);
$html2pdf->Output('exemple.pdf');

and the html is in print_s_template.ctp.

I found a solution myself. The problem is that I forgot to pass some variables to the View $view. And I suppose cake throw an error which, next, html2pdf cannot "render". So: double check that all the variables in the view do exist!
